Answer:

Step-by-step explanation:

The mean for all students is

[102(68.5) + 85(72.4)] / (102 + 85) = (6,987 + 6,154) / 187 = 70.27272727...

So YES the class average was a pass, but just barely.

Need help on this one too. If anyone would be willing to help, that'd be greatly appreciated. Thank you

Using the given information, we see that LOM + MON =LON. Now, we just substitute the expressions/numbers and simplify:
(2x+33)+(3x+20)=113
2x+33+3x+20=113
Simplify
5x+53=113
Collect like terms
5x=60
Divide by 5 on both sides to isolate x
x=12
Now we have found the value of x, we can find the value of MON.
MON = 2x+33
MON = 2(12)+33
MON = 24+33
MON = 67°

Ayo someone help me please
coldgirl [10]

Answer:

B. y= \left \{ {{x^{2}+4,\,x< 2 } \atop {-x+4,\,x \ge 2}} \right.

Step-by-step explanation:

The piecewise function consists in two functions:

(i) A vertical parabola directed in the +x direction and centered at V(x,y) = (0, 4) for all x \in (-\infty, 2). That is:

y = x^{2}+4, x < 2

(ii) A line with negative slope for all x \in [2, +\infty).

y = -x+4, x \ge 2

The correct answer is B.
